Description

Wave type power generation device

This case is related to a power generation technology, especially a wave type power generation device.

Referring to Fig. 1, a conventional wave type power generating device includes a base 11, a plurality of generators 12 (not shown) disposed in the base 11, and a plurality of left and right sides of the base 11. Actuating unit 13. Each of the actuation units 13 has a base 131 fixed to the base 11 , an actuation group 132 disposed on the base 131 and capable of pivoting itself, and a connection to the actuation group 132 and the respective A transmission group 133 between the generators 12 (not shown). Each actuation set 132 has a plurality of vanes 134 that are spaced apart from each other and that are rotatable about the same axis. Each of the transmission sets 133 is disposed on a respective base 131 and includes a first gear 135 coupled to each of the actuation sets 132, and a coaxial rotation with the respective generator 12 (not shown) and The second gear 136 is engaged by the first gear 135.

The principle of the wave-type power generating device is that the blades 134 of each of the actuating units 13 are rotated by the waves, so that the blades 134 drive the generators 12 (not shown) to generate electricity through the transmission group 133. The blades 134 of each of the actuation groups 132 are capable of coaxial rotation while absorbing the partial force provided by the converted waves. However, since each of the actuation groups 132 cannot move laterally, part of the force of the waves will be lost to the tapping. The actuating group 132 is fixed, and the seat body 11 cannot utilize lateral waves and is also pushed to the shore by lateral waves. In addition to the disadvantages of the force that cannot fully utilize the waves, the above-mentioned actuation group 132 is easily damaged and needs to be improved in the case of long-term wave-bearing force.

The purpose of the present invention is to provide a wave type power generating device which can utilize the thrust of the wave more efficiently and is more durable.

The wave type power generating device is adapted to be installed on the shore and generate electricity by using waves generated by the water. The wave type power generating device comprises a supporting unit, a power generating unit, a first transmission unit, a second transmission unit, a power generation transmission unit, and an actuation unit.

The support unit includes a seat body. The power generating unit is disposed on the base. The first transmission unit is disposed on the seat body and can be operated around the seat body. The second transmission unit is disposed on the base body and can be driven by the first transmission unit. The power generation transmission unit is connected between the power generation unit and the second transmission unit, and enables the second transmission unit to drive the power generation unit to operate. The actuating unit comprises a plurality of wave shields respectively disposed on the first transmission unit. The flow shields are spaced apart from each other in the direction of travel of the waves, and when the waves are pushed to move around the base in a running direction, the first transmission unit is driven to operate around the base.

The effect of the wave-type power generating device is that the wave-blocking device can completely absorb the striking force by moving when being slammed by the wave level, so that the thrust provided by the wave can be completely utilized, and also because the wave-proof plate can be horizontally The movement completely transforms the wave slap force, so the wave shields are not easily damaged and are quite durable.

The thickness of the offshore portion 39 is greater than the thickness of the proximal portion 38, such that the first embodiment is generally wedge-shaped, or generally triangular.

Each of the connectors 33 is a group of four. The connectors 33 of each set are disposed on the respective oblique brackets 322 and project toward the respective rails 311. Each of the connecting members 33 has a connecting rod 331 that connects the respective obliquely extending brackets 322, and an elliptical sliding block 332. Each slider 332 is threaded into a track 313 defined by a respective rail 311. The sliders 332 can also be circular or square in implementation.

The top plate 34 is disposed on the base 32 and has a base portion 341 and a plurality of partition portions 342 respectively connected to the base portion 341. The substrate portion 341 is recessed downward to define a buoyancy chamber 343. The baffle portions 342 are disposed in the buoyancy chamber 343 and divide the buoyancy chamber 343 into a plurality of buoyancy spaces 344 that can be filled and drained.

The power generating unit 4 includes a generator 41, and a power generating bracket 42 connected between the horizontal bracket 321 and the generator 41 connected to the base 32. Since the generator 41 can be used in many forms and is not the focus of the present case, it will not be described here.

The first transmission unit 5 includes a plurality of first reels 51 respectively disposed on the left and right sides of the base 32, and two actuating transmission belts 52 respectively disposed on the first reels 51. The first rotating wheels 51 are respectively pivotally inserted on the connectors 35 and located outside the left and right ends of the lateral brackets 324, respectively.

The second transmission unit 6 includes a plurality of second reels 61 respectively disposed on the left and right sides of the base 32, and a plurality of transmission wheels 62 respectively rotating coaxially with the second reels 61. Each of the second reels 61 is inserted at a portion where the transmission bracket 325 protrudes from the respective connector 35. The second reels 61 cooperate with the first reels 51 to support the actuating belts 52. Each of the transmission wheels 62 is also interposed on each of the transmission brackets 325 and located outside the respective second reels 61.

The power generation transmission unit 7 includes two power generation transmission belts 71 (only one of which is shown) connected between the power generation unit 4 and the second transmission unit 6. The power transmission belts 71 enable the transmission wheels 62 of the second transmission unit 6 to drive the generator 41 of the power generation unit 4 to operate.

The actuating unit 8 includes a plurality of wave shields 81 respectively disposed on the first transmission unit 5, and a plurality of baffles 82 and a plurality of stops 83. The wave shields 81 are pivotally spaced from each other along the wave traveling direction on the actuating belts 52 of the first transmission unit 5, and have an inland coastal side 811 and an offshore side facing the water. 812. Each baffle 82 abuts against the near shore side 811 of each respective wave shield 81. Each of the stoppers 83 is spaced apart from the offshore side 812 of each of the respective wave shields 81, and is located on the opposite side of each of the respective wave shields 81 from the respective baffles 82. Each of the baffles 82 has a triangular cross section and a height that is less than one-half of the height of the respective wave shield 81 and may vary slightly.

In the first installation of the first embodiment, if the horizontal brackets 321 of the base 32 are too high to be roughly aligned with the horizontal plane of the water, the buoyancy space 344 can be filled with water to make the seat. 32 Slightly sinking due to the weight of the water, the horizontal brackets 321 can be aligned with the horizontal plane. The advantage of the first embodiment in the form of a triangle or a wedge is that the bottom portion can be parallel to the land 2 during installation, so that it is not obstructed by the shore 2 during the adjustment movement.

Referring to FIG. 4, FIG. 5 and FIG. 6A to FIG. 6C, after the installation is completed, the first embodiment can generate power by using the wave's slap force. When the waves slap the wave shields 81, the wave shields 81 are supported by the baffles 82, so that they do not fall on the actuating belt 52 in the forward direction of the waves, but along the direction of the waves. Move and drive the actuating belts 52 to move. The wave shields 81 and the actuating belts 52 are respectively movable around the seat body 32 in a running direction T. The running direction T is in the same direction as the direction of advancement of the wave on the seat body 32, and is turned in the same direction as the backward direction of the wave when going down to the seat body 32, and then continues to be transferred. The seat body 32 is so repeated.

When the wave shields 81 are continuously operated, the actuation belts 52 respectively drive the second rotors 61 and the transmission wheels 62 (see FIG. 3) to operate. When the transmission wheel 62 (see FIG. 3) is in operation, the power transmission belt 71 (see FIG. 3) of the power generation transmission unit 7 is driven to drive the generator 41 to generate electricity. The second reel 61 and the transmission wheels 62 are not necessarily sized as shown in the drawings, and may be designed for large and small gears.

When the wave shield 81 is turned from above the seat body 32 to below the seat body 32, it is first hit by the water surface and is tilted toward the actuating belt 52. When the windshield 81 is tilted, it is supported by the stoppers 83, and does not completely fit on the actuating belts 52, but maintains the inclined state. This tilting state is less obstructive to the lower surface of the water than the erect state. When the windshield 81 is turned upside down, it is subjected to the reverse force of gravity and water, and assumes a state as shown in FIG. 6A, and when the wave shield 81 is again turned over the seat 32, Although still maintained in a tilted state, when the inclined wave shields 81 are again subjected to wave slaps, they can be righted as shown in Fig. 6B and continue to receive subsequent wave slaps.

The advantage of the seat body 32 of the first embodiment disposed on the slide rails 31 is that the seat body 32 can be along the rails 31 during the daily rise and fall of the seawater and the highest and lowest tides of the month. Move and automatically raise or lower to adjust the height without being submerged by the sea. For example, when the tide or tide is high, the seat body 32 is lifted by the buoyancy of the seawater, that is, it can move inland along the slide rails 31 and raise its height, and when the tide is low or small, the seat body 32 is pulled by gravity and moves along the rails 31 to the water to lower its height. The advantage of this automatic height adjustment design is that it ensures that the wave shields 81 are effectively slammed by waves, maintaining good power generation efficiency. The elliptical design of the sliding blocks 332 of the connecting members 33 can not only allow the sliding blocks 332 to move in the sliding rails 31, but also when the seat body 32 is affected by the fluctuation of waves and floats up and down. The non-circular design of the block 332 can also collide with the slide rails 31 to produce a stop effect, thereby preventing the seat body 32 from arbitrarily moving during non-rise and ebb tide times.

In summary, the effect of the first embodiment is that the wave shields 81 can completely absorb the slap force by lateral movement when subjected to wave slap, thereby fully utilizing the thrust provided by the waves, and also The wave shields 81 can efficiently convert the slap force by lateral movement, so that the wave shields 81 are also not easily damaged, and the present embodiment has a durable effect.

Referring to Fig. 7, a second embodiment of the wave power generating apparatus of the present invention is similar to the first embodiment except that the second embodiment has a wide width. In other words, the second embodiment lengthens the width of the lateral brackets 324, the transmission brackets 325, the wave shields 81, and the baffles 82, and increases the distance between the rails 311. In addition, in order to prevent the top plate 34 from being too large and causing excessive resistance, the second embodiment reduces the size of the top plate 34 and is connected between the top plate 34 and the horizontal brackets 321 by four support frames 9 to support the top plate. 34. On the other hand, in order to increase the supporting force, the first transmission unit 5 of the second embodiment further includes two first reels 51 respectively disposed at the center of the lateral brackets 324 (the figure shows only one of them is located above) The first reel 51) and an actuating belt 52 disposed on the first reels 51. The second transmission unit 6 further includes a transmission wheel 62 disposed at the center of the transmission bracket 325. It can be understood from the second embodiment that the present case can be slightly modified in accordance with the length of the coastline to be adapted to the coastline. The second embodiment of the present invention is a two-span implementation with respect to the single-span implementation of the first embodiment. Of course, it can also be three spans or more in implementation to take full advantage of the power generation between the long coastline and the waves.

However, the above is only the preferred embodiment of the present case. When it is not possible to limit the scope of the implementation of this case, all the simple equivalent changes and modifications made in accordance with the scope of patent application and the content of the patent specification in this case are still the patents of this case.
